Anti-Wall Street protesters’ plans to camp in a New York park throughout the city’s harsh winter were dealt a blow on Friday when the fire department confiscated six generators and about a dozen cans of fuel.

With the first snow forecast to fall on Saturday, the “Occupy Wall Street” movement against economic inequality lost the generators that had been powering heat, computers and a kitchen in the Lower Manhattan camp they set up six weeks ago.

“They think that taking the ‘power’ away will take the power away, and that’s absolutely not true at all,” said Occupy Wall Street spokesman Michael Booth.

The movement has sparked so-called occupations in cities across the United States and elsewhere in the world. But recent evictions in places like Oakland, California, where police used tear gas and stun grenades, have New York protesters on edge.
